ALBERT WILFORD, or LANSDOWNE, A YLAND.

C ONVEYER.

Application filed November To aZZ whm it may concern:

Be it known that I, ALBERT WVILFORD, a

citizen of the United States, residing at Lansdowne, in the county of Baltimore and State of Maryland, have invented new and useful Improvements in Gonveyers, ofwhich the following is a specification. I My present invention pertains to conveyers and more particularly to the type of conveyers employed in connection with grain elevators for delivering grain therefrom to vehicles of various kinds, the conveyer constituting the subject of my Patent 1,094,508 of April 28, 1914 being an example of said type.

The object of my present invention is the provision of the conveyer adapted in general to be easily handled and characterized particularly in the capacity of the tubular conveying means to be easily increased or diminished in length without subjecting the parts to undue wear so that the lifetime of the tubular conveying means will be materially prolonged.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed- 7 In the accompanying drawings, forming part of this specification:

Figure'l is a general view of the conveyer constituting the preferred embodiment of my invention.

Figure 2 is a sectional View, on an enlarged scale, illustrative of the tubular conveying means. 7

Figure 3 is an enlarged detail elevation of the same. v

Figure 4 is a transverse section taken in the plane indicated by the line 4-4 of Figure 3.

Figure 4 is a top plan view illustrative of the upper end of the intermediate, adjustable tubular conveyer section.

Figure 5 is a cross-section of the same.

Figure 6 is a view of one of the cable control devices.

Figure 7 is a detail view of the other cable control device.

Similar numerals designate corresponding parts in all of the views of the drawings.

I show in Figure 1 an elevator building 1,

and I also show a crane 2 projecting from said building and having a revoluble spout 3.

My novel conveyer is hingedly connected at 4 to said spout 3, and the upper section of the conveyer is in the form of a tapered 1, 1924. 'Serial No. 747,281.

head 5. A safety chain 6 is interposed between 'andconnected to the building 1 and j the head 5, but said safety chain does not act unless the hinge 4 breaks whereupon the safety chain will prevent gravitation of the conveyer.

Fixedly connected at 6* to and surrounding the lower portion of the head 5 is atubular casing 7, and connected to the casing 7 is a cable 8 which extends over guides 9 on an overhanging arm 10 carried by the building 1 and is designed to-be connected with the drum 11 of the device shown in Figure 6, the said device being of the construction illustrated or of any other construction adapted to take up and let off the cable 8' and adjustably hold the same.

Arranged withinthecasing 7 and appropriately connected at its'upper end to the lower end of the head 5 is an inner tubular conveyer section 12. The connection between said inner section 12 and the lower end of the head 5 is designated by 13, and it will be readily notedfrom Figure '2 that the tubular conveyer section 12 is spaced from'the casing 7. a

At 14 is, an intermediatetubular conveyer section which surrounds the section 12 and is interposed between said section 12 and the casing 7 and is endwise adjustable so that prefer, however, to connect a cable 15 to the section 14, as designated by 16 in Figure 1, and to carry the said cable 15 over a guide 17 on the head 5, and to connect the cable to the drum 18 of the device shown in Figure 7, said device being adapted for the taking up of the cable 15 and for the letting off of the same, and being also adapted to adjustably hold the cable 15 so as to retain the tubular section 14 in the relative position desired.

As will be understood by comparison of Figures 3 and 4 of the drawings, the casing 7 is provided at its lower end with rollers 20 which extend within the plane of the wall of the casing and are adapted by engaging the, section 14 to prevent undue wear of either the casing 7 or the section 14 incident to endwise movement of the section 14 in the casing 7. It will also be understood that the said rollers 20 will easethe movement be no liability of thesection 14 sticking car of the section 14 relative to the casing. 7 so that but little veffort Will be required for the raising of the section 14, and there Will and are designed by engaging either: the tubularsection, 12,:or -.the-icasing; 7;;to prevent sticking oi ;:the section 14.;a-nd. at atlie same time render easy the raising-;=of 'the section 14 While'lessening liability of Wear of either theisection .l4;;oiwtlie section 7 12 I or the-casing 7. zAszillustrated"therollers 30 are spaced :apartand :are looselyemounted on a ring '3l,',carried in avbar-rel' 3201i an an-nulus33. fixed .to the section 14, the said annulus being notched at 534401 the Qplay of the .rollersxBO, andrthe.barreli32 being disposed. at opposite sides sot each-rolleniit) so that: the'rollers are adequately maintained in spaced relation :and hence. are adapted to operate to the bestadvantage for 'tliepurpose stated. y
